Grandiflora rose plant named Macmouhoo

ABSTRACT

A new grandiflora rose plant producing near white flowers.

SUMMARY OF THE INVENTION

The present invention raltes to a new and distinct variety of rose plantof the grandiflora rose class which has as its seed parent the vareityknown as `Sexy Rexy` U.S. Plant Pat. No. 6,713, and as pollen point thevariety known as `Pot O' Gold.` The varietal denomination of this newrose is `Macmouhoo.`

Among the novel characteristics possessed by this new variety whichdistinguish it from its parent and all other varieties of which I amaware are its attractive near white flowers of hybrid tea qualityproduced in well-spaced clusters on a tall, free breaking plant.

Asexual reproduction by budding of the new vareity as performed inAuckland, New Zealand shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of the new vareity in different stages of developmentand depicted in color as nearly true as it is reasonably possible tomaek the same in a color illustration of this character.

Phenotypic expression may vary depending onlight, environmental and cultural conditions.
